Abstract (en)
[origin: EP2960226A1] To provide a liquid crystal compound satisfying at least one of physical properties such as high stability to light, a high clearing point, a low minimum temperature of a liquid crystal phase, small viscosity, suitable optical anisotropy, large dielectric anisotropy, a large dielectric constant in a minor axis direction, a suitable elastic constant and excellent compatibility; a liquid crystal composition containing the compound; and a liquid crystal display device including the composition. The compound is represented by formula (1): wherein, for example, R 1 is alkyl having 1 to 15 carbons, ring A 1 to ring A 4 are 1,4-cyclohexylene or 1,4-phenylene, at least one of Z 1 to Z 4 is -CF 2 O-, the remainder and W 1 are a single bond, - (CH 2 ) 2 -, -COO- or -CH 2 O-, X 1 is halogen, -C=N, -CF 3 or -OCF 3 , L 1 and L 2 are hydrogen or fluorine, Y 1 and Y 2 are fluorine; and a, b, c and d are 0 or 1, and a sum thereof is 1 or 2.
